Realistically, a strapless top is not the most sensible thing to wear if you're going to be doing acrobatics, unless she wants her (seemingly considerable) goodies flopping out. (below)Hip-hugging shorts like that are also difficult enough to keep up while doing cartwheels, let alone real acrobatic feats. A full-body spandex suit made sense for the same reason something like it made sense for Nightwing. Unless, that is, she's no longer acrobatic. Then, of course, the argument is moot. Shame, really, though, if that's the case. I thought that was part of what made her awesome.
